Machine Head is an American metal band from Oakland, California. Formed on October 12, 1991, the group was founded by vocalist and guitarist Robb Flynn and bassist Adam Duce. The current lineup of the band comprises Flynn, drummer Dave McClain, guitarist Phil Demmel, and bassist Jared MacEachern. Machine Head is one of the pioneering bands in the New Wave of American Heavy Metal.

Machine Head was formed by member Robb Flynn, previously part of the bands Forbidden and Vio-lence. Flynn felt musically unfulfilled with Vio-lence and requested to start a side project. When his request was denied, he left the band and formed Machine Head in 1991 with Adam Duce, Logan Mader and Tony Constanza. The band's first album Burn My Eyes, was a big success in Europe where it garnered attention on MTV's Headbangers Ball. In America (with HBB taken off the air during the grunge movement) Machine Head would not have success until later albums.
